Europe’s migration crisis involves not just the movement of people from outside Europe to the old continent, or from poorer states to richer ones, but also the movement of voters away from the centre, and of the displacement of the left-right division by one between internationalists and nativists.

When Bob Dylan blasted out his electric version of “Maggie’s Farm” at the Newport Folk Festival in 1965, he was, for many, committing sacrilege. Pete Seeger, who at the time epitomised American folk music tradition, was said to have called for an axe to cut the cables.

We can have democracy or we can have great concentrations of wealth, but not both, ‘people’s attorney’ Louis Brandeis warned. A new study shows the extent to which the super-rich were prepared to go to block Obama’s ambition to foster progressive change through government action.

The governing thread in a new selected Muldoon is a life lived from his upbringing in the village of Moy on the Tyrone-Armagh border to Princeton. The work engages concerns both private and public, while Muldoon’s poems address an increasingly wide audience.

The European Enlightenment made its mark in Ireland as well as elsewhere. In the middle decades of the eighteenth century there was optimism about improvement and progress, while at the same time poor harvests, famine and disease took off between 13 and 20 per cent of the population.

Should a book which contains passages clearly the product of imaginative re-creation be marketed as a biography? Jonathan Swift’s contradictions encourage many different kinds of response, but a work written in a highly imaginative style should perhaps be described as commentary.
